En effet, ce sont seulement les nouvelles traverses qui sont transportées sur des wagons de stockage accouplés au train de pose et qui sont acheminées, par des portiques et des transporteurs, depuis ces wagons de stockage, à travers le train, jusqu'à l'endroit où elles sont posées par le dispositif de pose des traverses, tandis que les nouveaux rails ou les nouvelles barres déjà soudés doivent être déposés préalablement de chaque côté du tracé de la nouvelle voie et laissés en attente. Une fois les nouvelles traverses posées sur le ballast, les rails ou barres sont pris par des pinces à rails munies de rouleaux, déplacés latéralement et posés sur les traverses. Toutes ces opérations se font pendant que le train avance d'une façon continue.The current laying trains, as described for example in patent application EP-A 0355 240 of the applicant, intended in particular for the renewal of sleepers and rails, are not designed to transport and handle the new rails on their wagons. Indeed, it is only the new sleepers which are transported on storage wagons coupled to the laying train and which are transported, by gantry cranes and carriers, from these storage wagons, through the train, to the place where they are laid by the device for laying the sleepers, while the new rails or the new bars already welded must be deposited beforehand on each side of the layout of the new track and left waiting. Once the new sleepers are installed on the ballast, the rails or bars are taken by rail clamps fitted with rollers, moved laterally and placed on the sleepers. All these operations are carried out while the train is advancing continuously.

Le wagon de manutention 5 se compose d'un châssis central 5a et d'une poutre mobile 23 montée coulissante sur celui-ci dans le sens longitudinal entre une position de travail déployée vers l'avant (figures 2, 4, 6) et une position de transport rétractée 23', comme indiqué en traits mixtes sur la figure 4. Sur ce châssis central 5a du wagon de manutention 5 et sur la poutre 23 sont installés des rouleaux de guidage 25 partiellement motorisés et formant le chemin de roulement supérieur pour les rails qui, dans leur position sur le chemin de roulement supérieur sont désignés par R2. En outre, il est prévu des installations coulissantes 27, déplaçables verticalement selon la double flèche F3 de la figure 5, pour descendre les rails des chemins de roulement supérieurs aux chemins de roulement inférieurs, comprenant des rouleaux 28 qui appartiennent dans la position haute aux chemins de roulement supérieurs et dans la position basse aux chemins de roulement inférieurs, comme cela sera expliqué plus tard en relation aux figures 9 et 10. Enfin, sur le châssis central 5a et sur la poutre 23 sont montés des rouleaux auxiliaires 29 (figures 2 et 6) ainsi que des stations de traction motorisées 30, (figures 2 et 5) appartenant aux chemins de roulement inférieurs.The
Une des stations de traction 30 suspendue au chassis central 5a est montrée sur les figures 11 et 12. Elle comprend un rouleau supérieur 38 motorisé et entraîné par un moteur-réducteur 39, ainsi que des rouleaux inférieurs 40. Le rouleau 38 est monté par l'intermédiare d'une tige télescopique horizontale 43 fixée au chassis central 5a, et d'une tige télescopique verticale 44, toutes les deux mobiles dans le sens des doubles flêches. Les rouleaux inférieurs 40 sont montés sur un bras 45 basculant dans le sens de la flèche courbée et articulé sur un support 42 fixé au chassis central 5a. Un système de serrage 41 travaillant avec un vérin permet de serrer le rail R3.One of the
Comme montré figures 9 et 10, les rouleaux de guidage 25 sont montés sur des cadres pivotants 24, qui sont articulés au châssis central 5a, autour d'un axe horizontal 24a. Les installations coulissantes 27 sont fixées de façon déplaçable verticalement par des montants 27a au châssis 5a, respectivement à la poutre 23 et peuvent être montées et descendues par des câbles tracteurs 27c entraînés par des treuils 27d. Ces installations coulissantes 27 sont munies à leurs extrémités inférieures de bras 27b portant les rouleaux 28. Dans la position levée illustrée figure 9, les nouveaux rails R2 qui arrivent sont supportés d'une part par les rouleaux 25 des cadres pivotants 24 et d'autre part par les rouleaux 28. Sur cette figure 9, les rails précédents se trouvant sur le chemin de roulement inférieur sont désignés par R3. Ce chemin de roulement inférieur comprend les rouleaux auxiliaires 29 lesquels sont montés au bâti 5b prévu au dessous du châssis central 5a.As shown in Figures 9 and 10, the
Les rouleaux de guidage 25 formant le chemin de roulement supérieurs et montés sur la poutre 23 sont liés à celles-ci par l'intermédiaire d'une double articulation 44 comme montré figure 9a, permettant de baisser le chemin de roulement en travail (à gauche de figure 9a), et de lever (à droite de figure 9a) pour pouvoir retracter la poutre 23 en position de marche haut le pied.The
Avant de faire descendre les installations coulissantes 27, avec les rails R2, dans la position basse, illustrée figure 10, il faut auparavant que les rails R3 soient reculés pour que ledit chemin de roulement inférieur soit libre. Ensuite, pour permettre la descente des rails R2, les rouleaux de guidage 25 sont escamotés au moyen des vérins 26 qui font basculer d'environ 90° les cadres pivotants 24 autour de l'axe 24a. Après la descente, les rails R2 supportés par les rouleaux 28 se posent aussi sur les rouleaux auxiliaires 29 (figure 10). Puis, ils sont pris par les stations de traction 30 qui font reculer ces rails dans une position telle que l'extrémité arrière des rails, maintenant en position R3 selon les figures 5 et 6, se trouvent en face de l'extrémité avant des rails R4 pour être éclissés à ceux-ci. Après l'éclissage, ils sont pris au dessous du wagon de pose 3 par les pinces à rails 21 pour être placés sur les traverses T1.Before lowering the sliding
Pour résumer, le train tel que défini par les revendications annexées comporte:
- des chemins de roulement supérieurs constitués par des dispositifs de tractions 10 et les rouleaux de guidage 11 sur le wagon de transport 1, les rouleaux de guidage horizontaux 18 et les rouleaux de guidage verticaux 19 sur le wagon de pose 3, au niveau desquels les rails sont désignés par R1, et enfin les rouleaux de guidage 25 sur le wagon de
manutention 5, au niveau desquels les rails sont désignés par R2; - des chemins de roulement inférieurs constitués par les rouleaux de guidage 20 et les pinces à rouleaux 21 sous le wagon de pose 3, au niveau desquels les rails sont désignés par R4, les rouleaux auxiliaires 29 et les stations de
traction 30 sur le wagon demanutention 5, au niveau desquels les rails sont désignés par R3; - et les rouleaux 28 sur les installations coulissantes 27 qui, selon leur position, font partie soit des chemins de roulement supérieurs, soit des chemins de roulement inférieurs.
- upper raceways constituted by
traction devices 10 and theguide rollers 11 on the transport wagon 1, thehorizontal guide rollers 18 and thevertical guide rollers 19 on the layingwagon 3, at which the rails are designated by R1, and finally theguide rollers 25 on the handlingwagon 5, at which the rails are designated by R2; - lower raceways constituted by the
guide rollers 20 and the roller clamps 21 under the layingwagon 3, at which the rails are designated by R4, theauxiliary rollers 29 and thetraction stations 30 on the handlingwagon 5, at which the rails are designated by R3; - and the
rollers 28 on the slidinginstallations 27 which, depending on their position, are part of either the upper raceways or the lower raceways.
Le déroulement des travaux s'effectue de la manière suivante:The work is carried out as follows:
Un train de transport avec des wagons de stockage 7 des rails R et des wagons de stockage des traverses T chargés, arrive sur le chantier et est accouplé au train de pose. La poutre mobile 23 du wagon de manutention 5 est déployée vers l'avant, dans le sens de la marche du train. Deux premiers rails R1 sont acheminés sur le wagon de transport 1 au moyen des dispositifs de tractions 10 qui les tirent du wagon de stockage 7 sur le chemin de roulement supérieur, à savoir sur les rouleaux de guidage 11, puis sur les rouleaux de guidage horizontaux 18 et verticaux 19 au moyen desquels ils sont centrés sur le wagon de transport 1, puis écartés après cette zone sur le wagon de pose 3 de façon à permettre la pose des traverses T. Puis, les rails arrivent en position R2 sur le wagon de manutention 5 sur lequel ils sont supportés par les rouleaux de guidage 25 sur des cadres 24 (Fig.9).A transport train with
Dès que les rouleaux de guidage 28 des installations coulissantes 27 se trouvent dans la position haute, les cadres pivotants 24 sont basculés de 90°, escamotant ainsi les rouleaux de guidage 25. Les deux rails supportés uniquement par le rouleau de guidage 28 peuvent être descendus par les installations coulissantes 27 sur les chemins de roulement inférieurs, à savoir sur les rouleaux auxiliaires 29, comme montrés pour les rails R3 sur la figure 9 et pour les rails R2 sur la figure 10. Ici Tes rails sont pris par des stations de traction 30 qui les reculent jusqu'au wagon de pose 3, où les rails en position R4 sont supportés et guidés par des rouleaux 20 et des pinces à rouleaux 21, en position écartée, comme illustrée sur la figure 13.As soon as the
Pendant cette manutention des rails, le portique 13, en se déplaçant sur les chemins de roulement continus 14, apporte les trente première traverses et les dépose sur le transporteur 16. Le train avance par ses propres moyens et les traverses sont posées par le dispositif de pose traverses 17, en cycles automatiques, à la distance prescrite.During this handling of the rails, the
Dès que les premières vingt traverses sont posées, les rails R4 sont centrés et placés sur les traverses T pour pouvoir être éclissées par l'intermédiaire des éclisses 37 au rail R5 posé dans l'intervalle précédente (Fig.13).As soon as the first twenty crosspieces are laid, the rails R4 are centered and placed on the crosspieces T so that they can be spliced through the
Entre-temps, les rails suivants sont acheminés sur le wagon de manutention et descendus dans la position R3 sur le chemin de roulement inférieur du wagon de manutention, comme illustré schématiquement figure 13.In the meantime, the following rails are routed on the handling wagon and lowered into position R3 on the lower raceway of the handling wagon, as shown schematically in Figure 13.
Ensuite, par rapport au train avançant, les rails R3 sont reculés jusqu'à l'extrémité avant des rails R4 par les stations de tractions 30 et sont maintenus stationnaires pour pouvoir être liées par des éclisses 37 aux rails R4, comme montré sur la figure 14. Pendant ce temps, les nouveaux rails sont acheminés sur les chemins de roulement supérieurs et descendus sur les chemins de roulement inférieurs dès que le train de pose est avancé d'une longueur de rail à poser.Then, with respect to the advancing train, the rails R3 are moved back to the front end of the rails R4 by the
La pose des rails qui vient d'être décrite peut s'effectuer à une vitesse de travail d'environ 300 m/heure.The installation of the rails which has just been described can be carried out at a working speed of approximately 300 m / hour.
Sur la figure 3, 4, les rails R3 et R4 se trouvant sur le chemin de roulement inférieur ont été dessinés écartés vers l'extérieur d'une façon exagérée de manière à ce que l'on puisse mieux les distinguer des rail R1 et R2 se trouvant sur les chemins de roulement supérieurs. En réalité, les chemins de roulement inférieurs et supérieurs se situent à la verticale l'un de l'autre.In FIG. 3, 4, the rails R3 and R4 located on the lower raceway have been drawn apart towards the outside in an exaggerated manner so that they can be better distinguished from the rails R1 and R2 located on the upper raceways. In reality, the lower and upper raceways are vertical to one another.
Après la pose de plusieurs rails, notamment après que les wagons de stockage des rails et des traverses ont été vidés, ces wagons de stockage sont évacués du chantier, alors que le train de pose peut rester en attente sur le chantier jusqu'à ce que les wagons de stockage nouvellement chargés reviennent.After the laying of several rails, in particular after the storage wagons for the rails and the sleepers have been emptied, these storage wagons are evacuated from the site, while the laying train can remain on standby on the site until the newly loaded storage cars return.
La pose des traverses et des rails qui vient d'être décrite constitue la première étape des travaux, et cette première étape est suivie d'une deuxième étape au cours de laquelle les rails sont soudés et puis fixés sur les traverses.The laying of the sleepers and rails which has just been described constitutes the first stage of the work, and this first stage is followed by a second stage during which the rails are welded and then fixed on the sleepers.
Cette deuxième étape se déroule de la manière suivante: une machine à souder, une installation de neutralisation des rails et une machine de tirefonnage pour la fixation des rails aux traverses, sont amenées sur le chantier.This second step takes place as follows: a welding machine, a rail neutralization installation and a threading machine for fixing the rails to the sleepers are brought to the site.
Après le démontage des éclisses 37, un certain nombre de rails sont soudés ensemble, notamment entre 6 et 12 rails selon la géométrie de la voie, pour former la première longue barre des 216 à 432 m, et sont également soudés avec les rails posés dans l'intervalle précédent. Puis cette première longue barre est neutralisée, c'est-à-dire amenée et maintenue à une température prescrite, et fixée aux traverses. Pendant la neutralisation et la fixation de la première longue barre aux traverses, la machine à souder avance et soude les prochains rails pour former la deuxième longue barre, et dès que la première longue barre est fixée aux traverses la machine à souder recule et soude la première et la deuxième longues barres ensemble; ensuite la deuxième longue barre est neutralisée et fixée sur les traverses, et pendant ce temps les troisièmes longues barres sont soudées et ainsi de suite.After dismantling the
